Abstract: 411,334. Indiarubber vessels. SEPTA SOC. ANON., 2b, Boulevard Royal, Luxemburg. Sept. 9, 1933, No. 25019. Convention date, July 31. [Class 66.] Pieces of unvulcanized rubber assembled in any desired shape are temporarily joined together either by their own adhesiveness or by clamps, &c., and are finally cemented together using latex as an adhesive. The latex is applied along the edges to be joined or on a narrow zone, so that it quickly dries. The rubber and/or the latex may contain dyestuffs, fillers, antioxidants, vulcanizing- agents, &c. After assembly the articles may be vulcanized. As shown in Fig. 1 a checkerwork of coloured and uncoloured crÛpe rubber is assembled by pressing the freshly cut edges together and latex is run along the dividing lines to form a sheet which when attached to an undersheet of rubber forms a bath mat. A cup, which may be used as a tapping cup for latex is made by assembling, in the same way, the two pieces of crepe rubber shown in Figs. 2- and 3. Specifications 211,515, [Class 70], and 397,644 are referred to.

Title: Improvements in gas detection and analysis
IPC: G01N21/37
Filed: 1947-09-25
Abstract: <PICT:0634453/III/1> In known gas analysing apparatus infra-red rays from a radiating source 2 are chopped by a wheel 18, and passed through chambers 3, 4 one containing the gas to be analysed and the other a neutral or standard gas, to detecting chambers 5, 6 filled with the gas for which the contents of chamber 3 are being examined. If any of the same gas as is contained in chambers 5, 6 is present in chamber 3, part of the energy of a particular band of infra-red rays is absorbed so that uneven comparison of the gas in chambers 5, 6 results.  The resulting pressure difference deforms a plate 13 forming one of the electrodes of a condenser or operating a moving coil or piezo crystal.  To reduce or indicate the effect of leaks in chambers 5 and 6 the contents of which are well below atmospheric pressure, the chambers are according to the present invention joined by a capillary leak in a diaphragm 13, and through a further capillary tube to a pressure-gauge 17.  Chambers 5 and 6 may be joined through a capillary leak to a reservoir of gas at the pressure of the detection chambers, or as shown, the whole apparatus may be surrounded by a reservoir 19.  The Provisional Specification states that the capillary tubes may be rolled flat or drawn out.
